To clarify my question, I have implemented the Hashin failure criteria in Abaqus/Explicit to modeling failure of orthotropic materials. However, the criteria only account for in-plane failures (i.e. tension, compression, and shear) in the principle 1 and 2 directions. Is there a way to include...
Hi Everyone,
I am trying to model the transverse shear fracture within each ply of a composite ply. I am wondering if Abaqus has any built-in failure criteria that I can use to do this because the default Hashin damage criteria only accounts for in-plane ply failure. If not, then what can I...
Hi Everyone,
I am running into some trouble trying to use Abaqus' built-in user subroutine ABQ_PLY_FABRIC to model ply failure in woven carbon fiber composite. I built the model in Abaqus CAE and modified the input code to change the material to ABQ_PLY_FABRIC according to the Abaqus...
Hi guys,
I am trying to model the behavior of a carbon fiber/epoxy curved beam with a 90 degree bend subjected to an opening moment at its ends. I am doing this with SR4 shell elements in Abaqus standard. But the resulting stiffness (i.e., moment/curvature) of the model always comes out to...
Rob,
Thank you very much for your response.
Yes, I have tried the using linear elastic constants and usually ended with the same "excessive distortion" message.
The model does behave correctly with both hyperelastic and elastic properties up until the point the program exits.
Because...
Hi,
This is the first time I am posting on Eng-Tip, so I apologize if my question sounds stupid. I am trying to model the compression/crushing behavior of a D-shaped rubber bumper used for cargo loaders. I have defined the bumper as a hyperelastic material with a Mooney-Rivlin model. The...
